- i Application filed January To all wkom z't may concern:

acitizen of the United States, residing at East Orange, in the county of Essex and 5 State of New Jersey, have invented certain 'new and useful Improvements in Bread- Baking Shells, of which the, following is a specification. I

The object of this invention is to provide a baking shell which may possess certain advantages affecting the baking process that characterize the bakin shell disclosed in my application-for U. Letters Patent Serial Number 46228, filed August 19, 1915,

and at the same time be considerably less e 'pensive to manufacture and more su'bstan-- tial and durable in construction, as well as -light in weight. r In the accompanying drawings, I

Figure 1 is a plan view of the improved a baking shell;

Fig. 2- isa sectional view taken longitudinally of one of the depressions, showing a piece of dough to form the loaf in place in the depression;

Fig. 3 is a sectional view 'on a larger scale of-one end. portion of the shell, taken transv versely of its depressions, and also, showing a piece of doughin place; and,

Fig. 4 is a view similar to Fig. 3, showing .the baked loaf, Fig. 5 showing a detail.

The'shell is composed of a rectangular piece a of sheet metal which is formed. fo-

6, throughout substantially the wholearea thereof.

At suitable intervals elongateddepressions margins f of each depression, if the depressions are made suitabl longer than the piece of dough to be bake ,they 'may rise more I precipitously from the bottom e, but in any event it is preferable that they form with the bottom rounded corners f, Fig. 2.

v The several edges'of! the sheet metal iecea are bent back upon themselvesin the orm of layers bearing flatwise against each other, as at g, and the thus rebent portions are bent up so as to form an upstanding wall, ,as'

' "shown. To make this wall continuous, the thus rebent egiles may be welded together at their ends. around the group 0 Specification of Letters Patent.

raminous, having preferably very fine holes:

margins d, at' least, of each depression risin gradually from its bottom e as for the en de'presan P Patented l ma, ieie. 15,1916. Seria1No.72,327 I i i sions there is left a plain or fiat portion -k- Be it known that 'I, ANTHONY P. PFEJL,

of the sheet which, ,with' the continuous double-thickness upstanding wall already described, constitutes a cross-sectionally an- I gular marginal reinforce on the shell, which not only affords a suitable rim but strengthens the shell (which would otherwise be flimsy and of insufficient strength, to resistthe handling incident to its use on account of the numerous perforations therein)" without adding materially to the weight thereof.

The present baking shell possessesall the advantages of that set forth in my application referred to in that it afiords a utensil in which the pieces of dough to be formed can be placed in a group and thereupon handled as a group in the transfer. from the r. W, wrnna,

forming table to the curing shelves and from v the latter to the hearth and in which the baking of the particular kind of bread for which it is intended (full-crust bread, like Vienna and French loaves and rolls, etc.)

can be accomplishedwith the same result" as to form of the baked loaves and uni-' and extensiveness of crust, as in "formity bread baked directly on the hearth; thatis to say, being foraminous thro1'1ghout, -the heat from the hearth directly reaches all parts of the loafwhich adjoin the shell, so that it becomes crusted as to the surfaceinext to the shell the same as it does at its exposed surface, while-the gradual elevation of the side margins of each depression gives the outlyingside portions of the loaf the'start to rise that I have found is indispensable if,

' in place of baking directly on the hearth, a utensil is. used (gradual elevation of the end margins of each depression having been found'not tolbeindispensable because. it is 'enough at the ends of the loaf if the .start to "rise is prompted bythe side. margins). In addition, the improved shell is stronger previous construction.

f The rounding of the corners f at the ends of the depressions has for its purpose to facilitate thebakers der the shell.

and at-the same time muchlighterthan my 1 very fine and close to ether. They are moreover formed by punc g the sheet from the This leaves a bur i on the inside at each hole, the efi'eotof which is to make the. loaf simulate the rougher appearance at the under peel being'introduced un'-- side which is to be the outside of the shell.

As before stated, the perforations b are r side of the loaf which any hearth-baked loaf has in comparison with a pan-baked loaf; in addition, the loaf when baked is cleaner at the under side because the burs form with the loaf a seal which prevents the draft through the holes from drawing up burnt particles of flour dust and other matter that acts to soil the leaf.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent is l. A baking shell consistingof a piece of sheet metal having one or. more baking depressions therein and flanking said depression or depressions on all sides thereof, a continuous marginal cross-sectionally angular reinforcing portion having one wall thereof substantially horizontal and the other wall upstanding, said shell being foraminous throughout substantially the whole of the area of each depression.

2. A baking shell consisting of a piece of i sheet metal having one or more baking dememos pressions therein and flanking said depres sion or depressions on all sides thereof a continuous marginal cross-sectionally angular reinforcing portion having one wall thereof substantially horizontal and the other wall upstanding, said shell being foraminous throughout substantially the whole of the area thereof-surrounded by said portion.

, 3. A baking shall consisting of a piece of sheet metal having one or more baking depressions therein and flanking said depression or depressions on all sides thereof a continuous marginal cross-sectionally angular reinforcing portion having one wall thereof substantially horizontal and the other wall upstanding and formed by bending the edge of the piece back on itself in the form of layers bearing flatwise against each other, said shell being foraminous throughout substantially the whole of the area of each de pression.
